Filed: 1992-02-10
Abstract: PURPOSE:To prevent contrast from being lowered by external light and to obtain a good video by arranging many screen members in a blind state and constituting the screen member turnable arround a shaft in parallel with its long side. CONSTITUTION:The oblong strip shaped screen member 7 of a screen substrate 6 is turnably attached arround a rotary shaft 8 which is parallel with a long side direction, and the screen member 7 can be fixed at an appreciate angle thetawith respect to the screen substrate 6. And the surface 7a of the screen member 7 is surface treated so that the surface diffuses and reflects the light made incident into the surface with appropriate directivity and processing for mat black coating or fiber flock planting processing, etc., are performed on the back surface 7b in order to absorb light made incident on the back surface 7b.

Title: Frequency discriminator
Inventor: ABE NORIO
IPC: H04N3/27
Filed: 1982-04-05
Abstract: PURPOSE:To cause no malfunction for any frequency, by providing a two state storing means whose storing state is switched complementarily in accordance with the outputs of the first and the second frequency discriminating means. CONSTITUTION:A titled device is provided with a two state storing means whose storing state is switched complementarily in accordance with the first frequency discriminating means output and the second frequency discriminating means output. At the time of reception of 50Hz, a -Q output of an FF8 sometimes causes a malfunction and becomes a high level. Also, at the time of reception of 60Hz, a -Q output of an FF81 sometimes causes a malfunction and becomes a high level. Even is case when a malfunction occurs in this way, however, an exact discriminating signal 9 is obtained from an RS-FF13. In this regard, in case when a noise is mixed at the time of receiving a 50Hz signal, sometime an output of the FF81 also executes a malfunction, but unless it coincides with a malfunction of the FF8, no malfunction output appears in the final discriminating output 9. In this way, it is possible to scarcely cause a malfunction even in case of any frequency.

Title: Heat transfer tube for water heater
Inventor: TSUBOI TAKAYOSHI
IPC: F24H9/00
Filed: 1989-03-10
Abstract: PURPOSE:To improve heat transfer efficiency and strength by providing an outer tube made of copper or copper alloy, and an inner tube made of copper or copper alloy, having an outer diameter of 30 to 90% of the inner diameter of the outer tube, inserted into the outer tube and secured to the inner surface of the outer tube. CONSTITUTION:An inner tube 2 in contact with an outer tube 1 is provided inside the tube 1. Accordingly, a heat transfer area inside a heat transfer tube is increased, and heat transfer performance inside the heat transfer tube is improved. The tube 2 is secured to the inner surface of the tube 1 to reinforce the tube 1, thereby improving the strength as the heat transfer tube. In this case, it is necessary to form the outer diameter of the tube 2 30 to 90% of the inner diameter of the tube 1. If the outer diameter of the inner tube is less than 30% of the inner diameter of the outer tube, heat transfer improving effect due to the increase in the heat transfer surface area is reduced. If the outer diameter of the inner tube exceeds the 90% of the inner diameter of the outer tube, a difference between the temperature of fluid flowing between the tubes 1 and 2 and the temperature of the fluid flowing inside the tube 2 is increased to lower its heat transfer performance. Thus, the outer diameter of the inner tube is 30 to 90% of the inner diameter of the outer tube, and desirably 50 to 60%.

Abstract: PURPOSE:To attain the simplification and reduction in cost of a toner grain supplying roller rotating means by making use of an electric motor disposed on an electrostatic copying machine, etc., as an electrically driving source rotating a toner grain supplying roller, and simultaneously, using an electromagnetic means and a specific cam mechanism, for the transmission control of driving force. CONSTITUTION:When the electromagnetic means 362 is energized, and a restraining member 364 is held at a nonacting position, the driving force of a rotary driving source for which the electric motor disposed on the electrostatic copying machine, etc., on which a main device is equipped, is used is transmitted to the toner grain supplying roller via a cam 346 and a lever member 342, and a supplying roller is rotated by the cooperative work of the driving force and a spring means 368. Therefore, it is unnecessary that a driving source exclusively used or the supplying roller is disposed. Further, the electromagnetic means 362 is not used for directly driving the supplying roller, so that the means 362 can be composed of a comparatively inexpensive solenoid, etc.
